Over 10,600 free low-poly models perfect for games and stylised scenes. API key required.

Enable each integration individually in the MCP for Blender sidebar panel inside Blender's 3D viewport. The tools for every integration are always listed in your AI client; each has a status tool (for example get_sketchfab_status) that tells the AI whether the integration is currently enabled.
Enabling an Integration
Open the MCP for Blender panel
In Blender's 3D viewport, press N to open the sidebar, then click the MCP for Blender tab.
Check the integration you want
Find the integration checkbox (for example, Poly Haven, Sketchfab, or Poly Pizza) and enable it.
Enter credentials if required
For services that need an API key, paste the key into the corresponding field. Keys are saved persistently in Blender's addon preferences.
You can also set API keys via environment variables in the environment Blender is launched from (not in your MCP client config, since the Blender addon reads them): BLENDERMCP_SKETCHFAB_API_KEY, BLENDERMCP_POLYPIZZA_API_KEY, BLENDERMCP_HYPER3D_API_KEY, BLENDERMCP_HUNYUAN3D_SECRET_ID, BLENDERMCP_HUNYUAN3D_SECRET_KEY, and BLENDERMCP_HUNYUAN3D_API_URL.
